In humans, the left side of the face (right hemisphere of the brain) is dominant in emotional expression. In rhesus monkeys, the left side of the face begins to display facial expression earlier than the right side and is more expressive. Humans perceive rhesus chimeras created by pairing the left half of the face with its mirror-reversed duplicate as more expressive than chimeras created by right-right pairings. That the right hemisphere determines facial expression, and the left hemisphere processes species-typical vocal signals, suggests that human and nonhuman primates exhibit the same pattern of brain asymmetry for communication.
在人类中，面部左侧（大脑右半球）在情感表达中占主导地位。在恒河猴中，面部左侧比右侧更早开始展现面部表情，且表现力更强。人类认为，将面部左半部分与其镜像反转复制品配对而成的恒河猴嵌合体比右 - 右配对产生的嵌合体更具表现力。右半球决定面部表情，而左半球处理物种典型的声音信号，这表明人类和非人类灵长类动物在交流方面表现出相同的大脑不对称模式。
